Abstract
L'invention concerne un procédé de nettoyage d'une installation de filtration du type comportant une pluralité de membranes immergées dans au moins une cuve contenant un effluent à filtrer, ledit procédé étant caractérisé en ce qu'il comprend les étapes consistant à: vidanger au moins partiellement l'effluent contenu dans ladite cuve de façon à exposer lesdites membranes à l'air; faire passer au moins une solution de nettoyage à travers lesdites membranes selon un flux inverse au flux de filtration de l'effluent, en amenant ladite solution de nettoyage du côté perméat desdites membranes.
